Canon Maxify MB 2150: black printing issue

Hello,

I use compatible cartridges for this printer.
However, recently the black printing quality has become very poor, while the initial work with this same cartridge was perfect.
Despite various cleanings and replacing the cartridge, nothing changes.
What can I do? What advice can be given to me?
Thank you in advance.
